Teaching ESL to adults means being awed every day as we witness the tenacity and perseverance of immigrants carving out better lives for themselves and their families. —Spelleri, 2002

berangan banana were treated with hot water at 50 ºc for 0 (control), 10, and 20 min and then kept at room temperature (25±2 ºc), 75-80% rh to observe the ripening progress. firmness and activity of cell wall degradation enzymes such as polygalacturonase (pg), pectin methylesterase (pme), and pectate lyase (pl) were determined for treated and untreated banana. the microstructure of banana peel ...

the pomegranate fruits of cvs. malas yazdi and malas ashkezar were immersed in sa (1 and 2 mm from source of acytyl salicylic acid) for five minutes, in ja (0.3 and 0.4 mm from source of n-propyl dihydrojasmonate) for fifteen minutes, in cacl2 (1 and 2%) for five minutes, and in distilled water for five minutes as control. then, the fruits were stored in cold storage at 1.5±0.5ºc and 85±5% rela...

production of part-baked bread is a successful method to postpone bread staling that has been applied widely for production of loaves. in this research, production and some physical characteristics of part-baked flat bread (barbari) including hardness, volume, color, weight loss, and microstructure were studied during the storage of the samples at ambient (25ºc) and freezing (-18ºc) temperature...

in this research, a novel formulation of sponge cake was studied. instant tea powder (itp) with high ester-catechins content was used to replace 0, 7.5, 12.5, and 17.5% of flour to make sponge cakes, hereafter referred to as the control, itp1, itp2, and itp3, respectively. the microbiological analysis and lipid oxidation experiments were conducted and the odor, flavor, color, chewiness, and ove...

We examine the case of items with a limited shelf-life where storing an item (before consumption) may carry a cost to a buyer (or distributor). For example, eggs, milk, or Groupon coupons have a fixed expiry date, and seasonal goods can suffer a decrease in value. We show how this setting contrasts with recent results by Berbeglia et al [4] for items with infinite shelf-life. We prove tight bou...

Shelf life of fresh fruits and vegetables is greatly influenced by environmental conditions. Increasing temperature usually results in accelerated loss of quality and shelf-life reduction, which is not physically visible until too late in the supply chain to adjust logistics to match shelf life. A blackberry study showed that temperatures inside pallets varied significantly and 57% of the berri...

this study examined sourdough lab containing specific starter cultures used to produce barbari-style bread and evaluated their microbiological shelf life and sensory properties. the effects of sourdough fermentation time (8, 16, 24h), fermentation temperature (28, 32, 36°c) and type of starter culture (lactobacillus sanfransicencis, atcc 14917; lactobacillus plantarum, atcc 43332; a mixture of ...

colour is one of the most important quality factors that can influence and determine the shelf life of canned chicken kebab. colour change is considered as unsuitable distasteful to consumers, indicating the end of a product's shelf life. in this study quality aspects of samples were examined over one month intervals after being prepared and while being stored under accelerated (44 °c) con...
